Although I'm not a Chabadnik in the true sense of the word I do attend a Chabad shul regularly and find a lot that makes sense in Chabad Chassidot. I find myself more religious than I used to be when I was younger (I'm 26 now) but I don't always know how to go about doing things even though I have a decent amount of knowledge on Judaism and definitely do believe in Torah v Mitzvot (as brought down from Moshe Rabienu...etc.)

Any advice for a guy who is still working on refining himself as a Jew?

you can try studying laws in the code of jewish law (abbreviated, by rabbi solomon ganzfried). perhaps laws on shabbos would be a good place to start.
there is a translation into english by hyman e goldin.
another translation is by rabbi eliyahu touger, published by moznaim publishing.
there are also other translations.
